Trainers, Pokemon Go will be undergoing server maintenance on June 1, 2020 and the game will be down globally for seven hours.
Here is the official announcement:
“Trainers,

Please have in mind that the following is just a tease and a hint, 0% confirmed and 0% a leak!
Back on April 16, 2020, the world’s best Pokemon Go dataminers discovered a new reward pool for level 41 through level 50. The “new level up reward pool,” or as they call it an educated guess (see the image below), starts from level 41 and goes up to level 50. There are various rewards, such as Ultra Ball, Pinap Berry, Incubators, and more. However, the required XP was not updated past Level 40.
Educated guess time!
We did a little manual number crunching with the information we had available in the current APK, and think we may have figured out some missing values from the Awards Levels we previously reported on.@OrangeHeart2018
